Mini ATE Diff/RSE/NRSE ?

[Grey]

Hi All,

I'm going to make a small ATE.

The DUT is DC to DC converter.

The input of the DUT is 24V DC .

It has 6 DC outputs

4 DC Outputs are having common ground source. That ground is connected to input -24V Supply ground.

remaining two output signals are having separate grounds.

i'm going to use USB6009 for DAQ device.

the USB 6009 is having max analog input voltage is 10 V. I will use 10 x divider probe for signals which are above 10v.

I need advise from you about connections which way i should go for ? shall i go for differential / RSE / NRSE ??

For better understanding i attached the DUT input out connections.

thanks.

Differential for signals 5 and 6 and RSE for signals 1-4.

If you're going to use a 10x divider make sure that USB DAQ will have enough precision on those signals to be valid/useful still.

Thanks asbo!
